Thanks!
I’m still going to mix up some acetone + ATF fluid though, as with spring here, there’ll be plenty of “fix-it” jobs which may need it, coming up. I may try a couple other solvents, too. Xylene, for example, has almost as low a surface tension number as acetone (should “wick” nicely), and evaporates into air much more slowly. However, Xylene also migrates through the sides of a polypropylene bottle much more rapidly than acetone, so, unless in use, it must be kept in a glass or metal container.)
If I get a great result with something, I’ll “report” back. I’d better bookmark this thread...
I’m going to try Mouse Oil on the frozen screws on my machine. It was the consensus of the gearheads that it’s the number one best product to free frozen bolts, etc. I also picked up some PB Blaster as a back-up.
I’m glad to know about the homebrew formula of ATF fluid and acetone. I can always fall back to that in future if I’m in a pinch.
Congrats on your project.
